Background Almost milliard people on the world suffer
from hypertension. Only about half of them is aware of
the illness. Each of patients should follow prescriptions
of drugs intake and the modification of life style. The
aim of the study was to evaluate the knowledge of hypotensive
treatment rules of patients with renal hypertension
and to specify how the theoretic knowledge is used
in practice. Above that the aim of the study was to determine
the educational nurse goal in the preparation of
patients to self control in hypertension and to establish
the educational program for subjects with renal hypertension.

Material and methods The study was made in 100 patients
with chronic kidney disease in various stages and
hypertension. The self-made questionnaire of survey was
used in the study. It contained 26 questions closed and
half-opened filled by the investigator during the talk with
patients or by the patients themselves. Questions involved
socioeconomic data, the knowledge of hypotensive rules
and the adherence to prescriptions. The subjective and the
objective knowledge was estimated. The questionnaire was
anonymous. According to weight and height BMI was assessed.
The patients were divided into four groups according
to age.

Results Group I — patients aged 20–40 years constituted
15%, group II — 41–50 years — 18%, group III — 51–60
years — 25% and group IV, the most representative group — above 60 years old — 42%. 32 persons were normal
weight, 35 were overweight, 24 had I degree obesity, 9 —
II and III degree. The abnormal BMI was observed
mainly in patients over 60 years old. Physical activity was
made mainly by overweight patients. Most of responders
(60%) were pensioners or retirees. Most of the study
population (55%) had middle educational background.
45% of patients made self blood pressure measurements.
More than half a patients (58%) didn’t fill the self control
diary. Patients with basic education considered their
knowledge about hypertension as adequate. There was
the correlation between education and the knowledge of
blood pressure value and methods of blood pressure treatment
(including nonpharmacological). 78 persons declared
the regular hypotensive drugs intake and 16 persons
— self modifications of drugs doses. Only about half
a study group knew about sodium restriction in the diet.
Solely 8% pointed that in renal hypertension not only
sodium should be avoided but also potassium. 42% admitted
drinking coffee, 26% — strong tea, 17% — alcohol
and 16% — smoking. 90 patients answered that stress
raised blood pressure.

Conclusions The patients’ knowledge about the renal
hypertension is not adequate and this knowledge is not
used fully in practice. Inadequate adherence to the therapeutic
prescription was also indicated. It is necessary to
rise the patients’ knowledge about self blood pressure
measurements and nonpharmacological methods of
hypotensive treatment. Therefore, the preparation of patients
to self control by educational nurses and the relevant
educational program in renal hypertension are important
points which may result in better control of that
kind hypertension.
